C axis milling

[jacobsiebold]

I am trying to mill flats on a round bar. No matter what I change in the X in the program it wants to mill on center. The only way to get it to work, is to change the Tool comp on the X and Z to half the flat width. I would like to be able to put the correct cutter comp in and have it come out. My code is below, TIA

You're only ever telling it to be on center. I think what you're trying to do is coordinate system conversion. That's G137. Then you just program in the XY path you're looking for and the control will figure it out.
